I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Growing and Maintenance Tips for Dahlia Decorative 'Blitzer' (Ships in Spring)

Planting: In spring, plant tubers 3 to 4 inches deep with the eye facing up, once soil has warmed to at least 60°F. Space 18 to 24 inches apart to accommodate their full, bushy growth.
Location: Full sun (6–8 hours daily) is essential for strong stems and prolific blooms.
Soil: Fertile, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Enrich with compost or aged manure before planting.
Watering: Water deeply once or twice a week, keeping soil evenly moist but not soggy. Avoid watering until shoots emerge to prevent rot.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift tubers after frost and store in a cool, dry place.
Fertilization: Apply a balanced fertilizer monthly or use a slow-release formula at planting and midsummer. Avoid high-nitrogen feeds to prevent leggy growth.
Pruning: Pinch back when plants reach 12 inches tall to encourage branching. Deadhead regularly to extend bloom time.
Pest & Disease: Watch for aphids, spider mites, and fungal issues. Ensure good air circulation and avoid overhead watering.
Propagation: Divide tubers in spring, ensuring each division has at least one viable eye.
